发明名称 Impulsive noise cancellation method and apparatus for low sample rate data
摘要 The present invention comprises an apparatus and method for substantially canceling impulsive noise from data. Such substantial cancellation is achieved by converting the time-domain data into its corresponding frequency spectrum, such that the impulsive noise threshold can be determined. Once such threshold is determined, all frequency components less than this threshold are canceled with the resulting spectrum being converted back to the time-domain. This substantially impulse free signal can then be substituted into the original signal where the impulsive noise occurs, thus, resulting in a signal having minimally distorted data that is substantially devoid of any impulsive noise. This signal may be further processed by an adaptive filter stage to substantially remove any remaining noise from the signal.
